It's the animation from valentines day it was part of milhouse's chase Lisa not sure why you're seeing it now and by herself
It kinda looks like 1/2 of the Valentines Day quest. Millhouse chased her and she ran. it was a 16 hour quest.
Either way that would be weird. Cause Millhouse isn't chasing her, and that quest is not in game anymore......
I know the person whose Springfield this is and they started playing after valentines update.
